Promote your own merchandise. While many YouTubers focus on the “direct” monetization routs available, perhaps the biggest potential in video is in the opportunity to promote other products and services that are moneymakers for you. Giving away free video content can be a great way to make money–if you’re effectively promoting merchandise or services that your free users will pay for. If you have products or services to sell and a YouTube audience that would be interested in purchasing them, this might be your best monetization opportunity.
Along with umpiring or refereeing a sport, athletic associations often pay good money for someone willing to coach local sports teams. Check your city’s want ad area for information about coaching community sports.
